Aim:
Myeloperoxidase (MPO) has been widely used as an inflammatory marker of both acute and chronic conditions. The aim of the present study was to analyze MPO found in the peri-implant sulcus fluid of implants (PISF) and gingival cervicular fluid (GCF) of natural teeth in healthy or diseased states.
Material And Methods:
A total of 107 dental implant sites, either healthy/noninflamed, inflamed or affected by periodontitis, were classified and GCF/PISF samples were obtained. GCF/PISF MPO was spectrophotometrically determined.
Results:
Both the GCF and the PISF volumes exhibited a gradual increase with gingival inflammation (P < 0.05). PISF from inflamed sites (P = 0.0001) and GCF from the gingivitis and periodontitis sites showed significantly higher total MPO levels (P < 0.05) in comparison with the noninflamed sites. The volumetric similarities of PISF and GCF in terms of response to inflammation were seen in the present study. However, some differences in PISF and GCF were observed.
Conclusion:
PISF may be suggested to have a considerable diagnostic potential as it exhibits the biologic changes around load-bearing endosseous dental implants.
